Helicopters standby for capsule

The Genesis probe, which left Earth in 2001 to gather particles blown off the Sun, returns its cargo on Wednesday. It will eject a capsule that will enter Earth's atmosphere at 40,000km/h before slowing, with the help of a parachute, to fall over the Utah desert. Hollywood stunt pilots are waiting to snatch the parachute in midair to prevent the capsule hitting the ground. Scientists hope the particles of solar wind can tell them about the evolution of the Sun and the planets.
